I really have no idea. The Hebrew version was that Yhwh was a tribal god that killed their enemies, gave them special privileges in return for worship, demanded constant blood sacrifice, and hated every group they hated. The Hellenized God of the NT is a universal god that forgives everyone who believes in a one-time blood sacrifice and replaced outright killing millions at a time with casting them into a lake of fire.
He didn't. There was just a necessary time of preparation before the Messiah. The new covenant only works with "the new birth" and Christ's accomplishment on the cross.
Former measures were stopgap ones to keep the people in line so they don't abandon God totally, or go totally depraved. In Galatians, Paul likens the way God had to deal with those earlier believers as like being a schoolmaster (Roman style) with tough discipline, but that the new covenant is like becoming a son, and attaining an inheritance.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
